Hawaiian sea turtle meat was once used for food and their shells fashioned into various tools and decorations for early Hawaiians. Although Hawaii placed regulations on hunting these turtles, it wasn’t until the designation by the U.S. Endangered Species act as a threatened species in 1978 that any real change began. There are many species of marine turtle within the Hawaiian islands, such as the Leatherback, Hawkbills and Green turtles. Greens are the most common Hawaiian sea turtle.
The Hawaiian green sea turtle is named for the green fat found under their shell. Being herbivores, they live primarily within Hawaii’s shallow lagoons where they can feed upon the lush sea vegetation and seagrass. Nesting within Hawaii occurs at O’ahu’s aptly named Turtle Bay. Unlike other species of sea turtle, that do not return to shore unless they are a nesting female, Greens will actually return to shore to bask in the sun. Before there were restrictions placed upon hunting greens, their skin was tanned and used for shoes and purses in. The Hawaiian green sea turtle has since been protected.
Hawaiian sea turtle facts involve the 3 types of marine turtles found there and where in Hawai they live. First is the green turtle, the most common, who is found in the shallow waters of the coastline. Then there is the hawksbill – which prefer to live within Hawaiian coral reefs. Lastly are the leatherbacks – found further off the coastlines of Hawaii, in more open deeper water. Although greens and hawkbills nest within areas of Hawaii, the leatherback does not and is found off of Hawaii on their way to other destinations. The Hawaiian “honu”, which means “of the turtle”, comes from the green turtle; which should be mentioned when discussing Hawaiian sea turtle facts.
Hawaiian sea turtle legend includes a tale of Kauila- a green turtle who was able to magically transform into a girl so she could look over and protect the children who payed along Punalu’s Beach. Kauila legend further tells that when Kaulia’s turtle mother was digging her nest to lay her eggs , a spring of water sprang forth from the hole which quenched the thirst of the island children. Kauila is considered the mythical mother of all sea turtles and is part of Hawaiin folklore still. Another Hawaiin sea turtle legend is that they are responsible for the populating of the islands – leading voyagers to the islands.
Baby Hawaiian sea turtles are only about 2inches and about 1 ounce when hatched. They are easy prey for crabs, mongoose, rats and other animals and few from each clutch survive to make it into the ocean. Another threat to these new turtles is the development of the shore and the artificial lights development brings. Theses bright lights often confuse the hatchlings and they crawl not towards the sea, but toward these lights and into dangers such as highways. Baby Hawaiian sea turtles will remain in the ocean until they reach about a foot in length then they return to the beach and start a cycle of swimming in the shore and sunning on their” home beach.”
Another cause of population decline involves a Hawaiian sea turtle disease called Fibropapillomatosis. This virus causes fibrous tumors to grow on the areas of soft tissues on the turtles. Not only confined to Hawaii- this virus is found worldwide. These tumors may also develop internally and affect the lungs, liver and kidneys as well as externally. Although primarily affecting the green turtle, it has been documented as involving all species currently. These tumors will continue to grow ,and especially internal tumors, eventually cause death. This virus is contagious and spread among sea turtles. Rescue Hospitals are seeing up to half of their incoming turtles as being afflicted with this hawaian sea turtle disease.
The Enchanting World of the Hawaiian Sea Turtle
Dive into the enchanting world of the Hawaiian Sea Turtle, a symbol of ancient wisdom and grace in the Pacific. These majestic creatures, known for their long lifespan and serene presence, play a crucial role in the marine ecosystems of Hawaii. With their scientific name Chelonia mydas, commonly referred to as the green sea turtle, they capture the imagination and hearts of both locals and visitors alike. This article embarks on a journey through the life, habitat, and unique characteristics of these remarkable reptiles, weaving scientific insights with captivating narratives to engage and educate.
Habitat and Distribution: Navigating the Hawaiian Waters
The Coastal Havens of Green Sea Turtles
Hawaiian Sea Turtles, particularly the Chelonia mydas, thrive in the warm and inviting waters surrounding the Hawaiian Islands. These coastal havens provide ample feeding grounds rich in seagrass and algae, essential components of the green sea turtle’s herbivorous diet. The shallow bays and protected lagoons serve as ideal habitats for juvenile turtles, offering safety from predators and abundant sunlight for basking—a behavior crucial for their thermoregulation and health.
Migratory Paths Across the Pacific
The migratory behavior of Hawaiian Sea Turtles is a marvel of nature, showcasing their incredible endurance and navigational skills. These turtles embark on long voyages, sometimes covering thousands of miles between their feeding sites and nesting beaches. Their ability to return to the exact beach where they were born, using Earth’s magnetic fields as a guide, remains one of the most fascinating aspects of their biology, demonstrating the intricate connections between sea turtles and the geomagnetic characteristics of our planet.
Anatomy and Physiology: Unveiling Turtle Secrets
The Armor and Agility of Sea Turtles
The anatomy of a Hawaiian Sea Turtle is a testament to millions of years of evolution, perfectly adapted to life in the ocean. Their streamlined shells, or carapaces, not only provide protection but also minimize drag as they glide through the water. These reptiles have powerful flippers that enable them to swim long distances with ease, demonstrating remarkable agility and strength. The design of their bodies reflects a perfect balance between durability and grace, allowing them to navigate the challenges of marine life.
Adaptations for an Aquatic Lifestyle
The physiology of Hawaiian Sea Turtles reveals a host of adaptations that facilitate their aquatic existence. Their ability to hold their breath for extended periods allows them to dive deep in search of food or rest. Moreover, specialized glands near their eyes help them maintain salt balance by excreting excess salt, a critical adaptation for animals that spend their lives in the ocean. These physiological traits, coupled with their slow metabolism, contribute to their longevity, with some individuals living over a century.
Interactions with Marine Life: The Turtle’s Role in the Ecosystem
Predators and Prey: The Circle of Life
In the vast ocean, Hawaiian Sea Turtles play a pivotal role in the balance of marine ecosystems. Juvenile turtles often fall prey to a variety of predators, including sharks and large fish, which is a natural part of the ocean’s food web. However, as adults, they face fewer natural threats due to their size and the protection offered by their hard shells. Their diet, mainly composed of seagrass and algae, helps maintain the health of coral reefs by preventing overgrowth of vegetation, which can suffocate corals and disrupt reef ecosystems.
Symbiotic Relationships: Turtles and Marine Inhabitants
The existence of Hawaiian Sea Turtles fosters symbiotic relationships with various marine organisms. For instance, cleaner fish and shrimps often feed on parasites and dead skin from the turtles’ shells and skin, providing a ‘cleaning’ service that benefits both parties. These interactions highlight the interconnectedness of marine life and the critical role that sea turtles play in maintaining the health and diversity of ocean habitats.
In conclusion, the Hawaiian Sea Turtle embodies the beauty and mystery of the marine world. Through understanding their habitats, anatomy, and ecological roles, we gain insights into the delicate balance of ocean ecosystems and the importance of preserving these magnificent creatures. Their continued existence is not only crucial for ecological health but also for cultural heritage, symbolizing resilience, navigation, and the interconnectedness of life.
FAQs about Hawaiian Sea Turtles

This diet helps maintain the health of the coral reefs by controlling the growth of vegetation that can otherwise overwhelm coral ecosystems.
How long can Hawaiian Sea Turtles live? Hawaiian Sea Turtles are known for their impressive lifespan, with many individuals living up to 80 years or more. Their longevity is attributed to their slow metabolism, adaptive physiological traits, and the protection afforded by their hard shells, especially once they reach adulthood and have fewer natural predators.
How do Hawaiian Sea Turtles navigate the ocean? Hawaiian Sea Turtles possess an extraordinary ability to navigate across vast ocean distances, a skill they utilize during their migratory journeys between feeding grounds and nesting sites. Scientists believe they use Earth’s magnetic fields as a navigational tool, allowing them to return to the exact beach where they were born to lay their eggs.
Why are Hawaiian Sea Turtles important to the ecosystem? Hawaiian Sea Turtles play a vital role in marine ecosystems, particularly in maintaining the health of coral reefs. By feeding on seagrass and algae, they prevent these plants from overgrowing and suffocating coral reefs, which are crucial for marine biodiversity. Additionally, their interactions with other marine species, such as cleaner fish, help promote a healthy and balanced marine environment.
How do Hawaiian Sea Turtles reproduce? Hawaiian Sea Turtles have a unique reproductive process where females return to the beaches where they were born to lay their eggs. After mating in the water, the female comes ashore, digs a nest in the sand, and lays a clutch of eggs. She then covers the nest and returns to the sea. The eggs incubate for about two months before the hatchlings emerge and make their way to the ocean, guided by the natural light reflecting off the water.
